Title: Plasma processing equipment
Inventor: UKAI KATSUZO
IPC: C23F4/00
Filed: 1988-11-11
Abstract: PURPOSE:To improve plasma processing characteristics by burying a main electrode and a ring type electrode arranged around the main electrode in the vicinity of a substrate mounting surface in a substrate stage composed of insulative material, and applying a DC voltage of potential inverse to the main electrode to the ring type electrode. CONSTITUTION:Since a substrate is subjected to etching process not in the horizontal state but in a vertical state, in order to retain the substrate 4 before plasma is generated and after the plasm is eliminated, a circular plate type electrode 7 and a ring type electrode 6 arranged around the electrode 7 are buried in a substrate 3 of insulator like ceramic. The electrode 7 is connected with a DC power supply 60 via a high frequency electrode 2, a high frequency filter constituted of a coil 62 and a capacitor 63, and a switch 61. The electrode 6 is connected with a DC power supply generating a voltage inverse to the DC power supply 60, through a through hole 12 insulated from the electrode 2, and via a switch 71. As a result, when plasma is not generated, the substrate 4 can be retained while high voltages of mutually inverse potential are applied respectively to the circular type electrode 7 and the ring type electrode 6.

IPC: H01L21/762
Filed: 1985-12-20
Abstract: PURPOSE:To reduce the resistance of a buried layer by using a low resistance silicide buried layer as the buried layer of a dielectric isolation substrate. CONSTITUTION:A buried layer 3 consists of a high concentration Sb diffusion layer 10 and a molybdenum silicide layer 11. The high concentration Sb diffusion layer has been used in a substrate of conventional construction and the sheet resistance is 30OMEGA/unit but 4OMEGA/unit in the MoSi2 layer. Consequently, by using both the high concentration Sb diffusion layer 10 and the MoSi2 layer 11, the sheet resistance can be reduced to approx. 12% in comparison with the case of using only the high concentration Sb diffusion layer. A construction of providing an Si3N4 layer 12 between the MoSi2 layer 11 and an SiO2 layer 13 also has the following effect. Even if a MOS element is manufactured on the substrate in a manufacturing process which includes 1,200 deg.C heat treatment, the shet resistance is not varied by the effect of the oxygen of the SiO2 film 13 to the MoSi2 layer 11 and even after the formation of the element, the insulation characteristic of the film is not deteriorated.
